109225 ÷ 12 
We're looking to find how many times 12 goes into 109225.

Let's proceed to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

On to step 2:
10 divided by 12 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 12

Step 3:
If we divide 109 by 12, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 108 from 109, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 12

Let's proceed to step 4:
12 divided by 12 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 12 from 12 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 12

Let's proceed to step 5:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 910.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 12

On to step 6:
If we divide 25 by 12, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 9102.0
Subtract 24 from 25 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 12, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9102.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 9102.08
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 9102.083
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 9102.0833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 9102.0833, and the remainder is 4e-05.
